Latest Progress on Shaanxi Jingyi Chemical Co., Ltd.’s 500,000 tons/year Coal Tar Deep Processing and Multi-product Integrated Utilization Project. Author/Source: Huahua Network – Coal Chemical Industry. Date: July 15, 2019. Clicks: 11. At 17:38 on July 10, the 10kV and 380V plant power supply systems for the power center of Shaanxi Jingyi Chemical Co., Ltd.’s 500,000 tons/year Coal Tar Deep Processing and Multi-product Integrated Utilization Project were successfully connected to the power supply. The power supply area this time includes sections I, II, III, and the standby section of the 10kV power station. 400V plant #0 section, #1 section, #2 section, standby section. At present, all sections are energized and operating normally, with all instruments and signal indications being accurate. To ensure that all preparatory work was done correctly prior to power reception, the various participating units organized everything meticulously and enforced strict standards; the personnel involved in the power supply process communicated and coordinated actively. At 10 a.m. on July 10th, the Power Center officially began the power reception process. During the power reception process, the on-site operators strictly followed the prescribed procedures for carrying out inspections, operations, and record-keeping. More than 300 switching operations were performed, along with a large number of secondary measurements, and not a single error occurred throughout the entire process. After more than 7 hours of work, the task of connecting the plant’s auxiliary power supply at the power center was successfully completed. Shaanxi Jingyi Chemical Co., Ltd.’s 500,000 tons per year project for the deep processing and integrated utilization of coal tar involves the use of advanced technologies with independent intellectual property rights, developed specifically for the characteristics of coal tar. The core technology consists of a combination of boiling-bed hydrogenation for quality improvement of coal tar across all fractions, along with fixed-bed hydrocracking; using medium- and low-temperature coal tar as raw material, this process primarily produces high-value aromatic chemical products. The project covers an area of about 1,200 mu, with an estimated investment of around 4.6 billion yuan. Construction of the project officially began in August 2017, and it is now in the final stages of design, civil works and safety preparations, as well as equipment installation. Completion and commissioning are expected by the end of October 2019. The projects mainly include: a 550,000-ton/year coal tar pretreatment unit, a 500,000-ton/year coal tar fluidized-bed hydrocracking unit, a 450,000-ton/year coal tar fixed-bed hydrocracking unit, a 400,000-ton/year naphtha continuous reforming unit, a 170,000-ton/year aromatic extraction unit, a 50,000 cubic meters per hour coal-to-hydrogen unit, a 50,000 cubic meters per hour air separation unit, a 100,000-ton/year methanol synthesis unit, as well as related supporting facilities such as hydrogen purification (PSA) units, sulfur recovery units, phenol-amine recovery units, storage and transportation systems, and other auxiliary and environmental protection systems.
